I love Closure in Moscow for being able to sound poppy/catchy enough that they'd feel at home on my local rock station, but at the same time playing with odd timings and complex song structures.

Vanguard has like 6 completely different sounding parts to the song (as opposed to verse - chorus - verse - chorus) all squeezed into a sub 4min song. It's quite amazing how much these guys can pack into such consumable songs.
